, but according to police, the camera captured a still photograph of him installing the camera. After it was hidden in the ceiling, the camera did take still photographs of "three to four adult women" in various stages of undress during the evening hours of March 8, said Capt. John Cooney. It was discovered by one of the victims, who saw something wrong with the ceiling and upon closer inspection noticed it appeared to be a camera lens. The victim notified authorities at RPI who, in turn, called Troy police. Cooney said McMartin, a heating and cooling supervisor at the college, took some time to set up a mount in the ceiling and while attaching the camera -- a type used by hunters to see if deer are frequenting a certain area -- to the mount, he inadvertently took a photo of himself. "We have recovered numerous still photos which do indicate numerous female adults in various stages of undress, and we have recovered digital evidence which implicates the defendant," Cooney said. While the locker room near the Robison Pool is used by high school students and adolescents, Cooney said the photos confiscated by police are exclusively of female adults and only from March 8. Troy police are in the process of contacting the victims so they can file formal complaints, which will help solidify the case against McMartin, Cooney said. The investigation is continuing and "it may take detectives down another road," but Cooney said McMartin told police March 8 was the first and only time he set up such a camera. There is also no evidence that the images were disseminated in any way, Cooney said. "As disheartening as it is to see these actions on the part of the defendant, I think we need to send a message that we do feel, without question, it is extremely limited as far as the exposure to the victims goes," Cooney said. "Although we will look elsewhere to see if there are any other victims out there, we are fairly comfortable that there are probably not many more victims than those on March 8 and the images on the defendant's camera have not gone on the Internet or anything like that." McMartin, who was honored for five years of service at RPI in September 2011, was immediately fired and barred from all buildings on campus, according to a statement sent by the college on Thursday. RPI, according to the statement, is conducting a thorough search of all bathrooms and locker rooms as a precaution. McMartin also works as a part-time, seasonal employee at the Saratoga National Historic Park. Officials there would not comment on the case on Thursday. McMartin, with his attorney Peter Moschetti, pleaded not guilty in front of Troy Judge Chris Maier to the felonies of unlawful surveillance and burglary. The latter charge was lodged because he did not have the authority, or any reason, to enter the locker room where he stashed the camera. Given the fact McMartin has strong ties to the community and did turn himself in to authorities, Maier set bail at $5,000 cash or bond and turned the matter over to a grand jury. James V.
